You can build universal on any Mac, Intel or PowerPC. The default
universal_archs on Leopard and Tiger are ppc i386. On Leopard this is
straightforward, because Leopard is a universal operating system, as is Tiger
on i386. But Tiger on PowerPC was not a universal operating system so that's
more difficult. You have to use the MacOSX10.4u SDK to get the universal bits.
MacPorts should handle this automatically for autotools ports, but for other
ports you have to figure out where to put the ${configure.sdkroot} variable
yourself. And because Tiger on PowerPC is the only system where it matters, and
there are so few users on that system anymore, it's likely there are numerous
ports where this has not been done correctly, so encountering problems on that
system is likely.
